GEARING FOR AWNIN GS.

To all whom it may concern:

Be it known that I, EDMUND ROSENBERG, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Gearing for Awnings; and I do declare the following to be a full, clear, and exact description of the invention, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon,-

which form a part of this specification.

This invention relates to awnings, especially to the class of awnings that are of relatively large size that are designed to be used on the walls of buildings such as the fronts of mercantile houses or factories, the invention hat'ing reference particularly to gearing for operating the awnings so that they may be either rolled up or unrolled at pleasure.

Objects of the invention are to provide improved gearing for roller awnings that will be adapted for universal application and permit of the different parts being mounted cheaply against buildings; and to provide gearing that may not only be quickly adjusted to the walls of the buildings, but which will be relatively light in Weight and be strong, durable and economical in use.

The invention comprises certain novel features relating to the awning roller and the housing thereof and also a crank-box and connections between the crank-box and the roller, the invention consisting further in the parts and combinations and arrange ments of parts as hereinafter particularly described and defined in the appended claims.

Referring to the drawings Figure 1 is a fragmentary front elevation of an awning and gearing constructed substantially in accordance with the invention; Fig. 2, a ver tical sectional View approximately on the line A A in Fig. 1; Fig. 3, an end view of the awning roller; Fig. 4, a sectional view of a portion of the roller approximately on the line B in Fig. 3; Fig. 5, a front view of a gear wheel for operating the roller; Fig. 6, an end view of the socket connection of the gear wheel; Fig. 7, a perspective View show ing an end part of the drive shaft of the gear wheel shown in Fig. 5; Fig. 8, a front View of the crank-box without its cover or front; Fig. 9, a front View of the base of the crank-box; Fig. 10, a perspective view of the housing of the roller gearing; Fig. 1].,

Serial No. 408,852.

a perspective view of one of the wall parts of the crank-box; and, Fig. 12, a perspective view of the other one of the two wall parts of the crank-box.

Similar reference characters in the various figures of the drawings designate like elements or features of construction.

In Figs. 1 and 2, the numeral 1 designates a foundation board or part of a building, and 2 another foundation board or a building wall for supporting the awning roller and gearing; 3, designating the body of the awning roller, and 41 the awning composed of canvas or other suitable material. The body of the roller is preferably composed of wood and has metallic sockets 5 and 6 on its ends for rotatively supporting the roller, one socket being provided with a journal '7 mounted in a bearing 8 that is attached to the member 2. Each socket preferably has a slot 9 therein through which the fabric awning extends to the body of the roller to which it is suitably attached, so that the awning may have the maximum width between the bearings of the roller, the socket 5 being provided with a journal 10 for its support.

housing for one end of the roller coinprises a plate 11 having bolt holes 11 and adapted to be bolted against the wall of the building, the housing having a journalbean ing 12 supporting the ournal 10 and provided with a cap 13. The socket 5 has a squared part 14. adjacent to the journal 10 and has a gear wheel 15 mounted thereon, said wheel having spherically shaped teeth 16 connected by a ring 17 that extends about the extremities of the teeth and serves to strengthen them, and also to prevent the edge of the awning when being rolled up from being drawn into the teeth. The housing com prises also a bearing 18 connected by plates 15) and 20 to the bearing 12 and provided with a cap 21, there being a bearing 22 in alinement with the bearing 18, and provided with a cap 23 adjacent to the bearing 12. A socket 2t has its exterior journaled in the bearing 18 and its cap'21 and has a flange 25 engaging the upper side of the bearing and its cap, the socket luwing a short spindle 2G journaled in the bearing 22 and its cap 23, there being a lug 27 on the body of the socket 2% in engagement with a wheel hub 28 hav ing gear teeth 29 on the spindle 20, the teeth 29 being in engagement with the gear teeth 10. The socket 2t has four recesses 30, 31,

32, 33 therein, and serves as a part of a universal coupling for driving the awning roller by means of the two gear wheels above-de scribed.

An improved crank box comprises a base 34: having bolt holes 34 and having also a flange 35 at the front thereof, the base being adapted to be bolted against the front of the building at a suitable distance below the awning roller, so as to be within reach of a person on the ground. The body or walls of the crank-box comprise two principal parts, the upper wall 36 having two side wall parts 37 and 88 formed integrally therewith, the wall 36 having a journal bearing 39 therein, the other principal part comprising a lower wall 40 having two side wall parts 41 and t? formed integrally therewith and adapted to abut the wall parts 37 and 38, said wall parts fitting closely against the inner side of the flange The wall 40 has a journal hearing 43 formed on the inner side thereof, and has a suitable member in which is a shaftguide 44. The crank-box has a front or cap 45 suitablybolted against the body walls and holding them securely against the base A bevel gear wheel 46 is suitably journaled in the bearing 39 and has a socket 47 therein formed like the interior of the socket 2st above-described and shown in Fig. 6. A rotative shaft 418 of suitable length has suitably attached end parts 49 and 50, each end part having four lateral projections 51, 52, 53, 5st inserted in either socket 2% or 47, and permitting the shaft to be arranged at different angles to the perpendicular or axes of the rotative members that are mounted in the bearings 18 and 39. A bevel gear wheel 55 has a ournal 56 mounted in the front 45 and engages the wheel t6, the inner side of the wheel 55 being guided laterally by the guide 4A, and against the side of the bearing t3, the lower side of the wheel 46 being guided in the bearing 43. The shaft of the wheel 55 has a squared part 57 and a squared terminal end 58 adapted to receive a crank arm for operating the gearing. A sliding gravity latch bolt 59 is mounted in guideways 60 and 61 of the upper and lower walls respectively of the crank-box, and has an open ing 62, the sides of which are adapted to engage the squared part 56 to prevent rotation thereof when the latch bolt is in its normal lowermost position, there being an enlarged part 62 of the opening adapted to permit ro tation of the squared part 56 when the latch is elevated.

In practical use, in many cases it is desirable and may be necessary to place the crankboX in an arbitrary position with respect to the awning roller, the distances between the two being in some cases greater or less than in others, and after the roller has been suitably mounted in a desired position and a crank box attached to the building, measure ments may be taken and the shaft 48 may then be cut to the desired length, so as to be connected to the end parts 49 and 50. Normally the latch bolt 59 will prevent operation of the gearing and must be elevated and so held while operating the gearing, either to elevate or to lower the awning. In operating the gearing any suitable crank arm or wrench may be applied to the squared end 58 which projects beyond the front &5 of the crank box, so as to rotate the shaft 48 and consequently rotate the awning roller in a desired direction. It will be understood from a description of the mechanism, that in most cases the awning will not descend of its own accord and turn its gearing, so that accidents from such cause are not liable to happen, it usually being necessary to manually operate the gearing.

Having thus described the invention, what is claimed as new is- 1. Awning gearing including a crank-box, a wheel journaled in the crank-box and having a socket therein that has a plurality of recesses in the inner side of the wall thereof, a gear wheel journaled in the crank-box and engaging the gear Wheel that has said socket therein, and a drive shaft having an end part connected thereto provided with a plurality of lateral projections, the end part extending into said socket with the projections thereof in said recesses.
